## Installation

Atom Package: https://atom.io/packages/atom-beautify

```bash
apm install atom-beautify
```

Or Settings/Preferences ➔ Packages ➔ Search for `atom-beautify`

### Important Notice: Analytics

By default `Anonymous Analytics` is enabled.
If you do not wish to have usage data sent to Google Analytics then please disable `Anonymous Analytics` option before using Atom-Beautify.
See [`Anonymous Analytics` section of docs](docs/options.md#anonymous-analytics) for details.
Thank you.

### Next Version: [Unibeautify](https://github.com/Unibeautify/unibeautify)

Atom-Beautify is going to be completely rewritten with [Unibeautify](https://github.com/Unibeautify/unibeautify) at its core!
See [`unibeautify` branch](../../tree/unibeautify) for work in progress and [Issue #1174](https://github.com/Glavin001/atom-beautify/issues/1174).

## Beautifiers

Some of the supported beautifiers are developed for Node.js and are automatically installed when Atom-Beautify is installed. However, other beautifiers are command-line interface (CLI) applications and require you to manually install them.

## Usage

Open the [Command Palette](https://github.com/atom/command-palette), type `Beautify`, and run `Beautify Editor`.

![image](https://cloud.githubusercontent.com/assets/1885333/16542583/1c8d975c-4085-11e6-8307-e35df7430a10.png)

### Selection of Code

It will only beautify selected text if a selection is found -- if not, the whole file will be beautified.

| Selection of Code | Beautify Selection of Code | Beautify Entire File |
| --- | --- | --- |
| Select code in Atom editor | Only that selection is beautified | Without a selection all code is beautified |
| ![image](https://cloud.githubusercontent.com/assets/1885333/16542597/b3f90c84-4085-11e6-8a0e-1b8604ae385c.png) | ![image](https://cloud.githubusercontent.com/assets/1885333/16542598/b5a86b10-4085-11e6-80cf-0afaf1a819c3.png) | ![image](https://cloud.githubusercontent.com/assets/1885333/16542603/b798ec24-4085-11e6-880e-8d3a2741940f.png) |

### Beautify On Save

`Beautify On Save` can be enabled for each language individually.

For example, for language `HTML` go into Atom-Beautify's package settings (`Atom` ➔ `Preferences` ➔ Search for `atom-beautify`), find `HTML`, and toggle the `Beautify On Save` option.

![atom-beautify-setup-beautify-on-save](https://cloud.githubusercontent.com/assets/1885333/16542692/3e781e74-4089-11e6-9cf2-5a19af161093.gif)


### Keyboard Shortcut

You can also type <kbd>Ctrl</kbd>-<kbd>Alt</kbd>-<kbd>B</kbd> as a shortcut or click `Packages > Beautify` in the menu.

#### Custom Keyboard Shortcuts

See [Keymaps In-Depth](https://atom.io/docs/latest/behind-atom-keymaps-in-depth) for more details.

For example:

```coffeescript
'.editor':
  'ctrl-alt-b': 'atom-beautify:beautify-editor'
```

## Configuration

Edit your `.jsbeautifyrc` file in any of the following locations:

- Atom Package Settings
  `Atom` ➔ `Preferences` ➔ Search for `atom-beautify`
- Same directory as current file
- Project root
`atom-beautify` will recursively look up from the current file's directory to find `.jsbeautifyrc`.
- Your user's home directory

**Note**: *Comments are supported in `.jsbeautifyrc` thanks to [strip-json-comments](https://github.com/sindresorhus/strip-json-comments).*

See examples of both ways inside [`examples/`](examples)

See [all supported options in the documentation at  `docs/options.md`](docs/options.md).
